I’m not surprised that they didn’t learn anything from the impromptu Chinese carry-out picnic.
I’m a little disappointed that they didn’t even learn that it’s okay to take carry-out to a picnic.

Don't even ask about the tuna night.
That's not fair.
Thank you. That conclusion is never reached on one's own here.
How can you allude to something called the tuna night and say I can't ask about it?
